Hi,
Considering that you ask the question in Office 2016 for Mac forum, are you using Excel for Mac?
Could you provide more information about the data source you use to create map chart? If I have your sample, it may help me better analyze the issue for you.
There is an official articles on Map chart for your reference: Create a Map chart in Excel;
There is a known issue where Map Charts which make use of
Geography Data Types can sometimes map incorrectly. Please try to include Admin Fields, such as Province or Country when attempting to plot these until the problem is fixed.
Any updates, feel free to post back to let us know.
Best Regards,
Herb
